Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked genetic disorder characterized by low levels of the G6PD enzyme. It is present worldwide but with more prevalence in the Middle East and the Mediterranean areas. We report a case of severe hemolysis due to G6PD deficiency manifesting as methemoglobinemia in a 70 year old Omani male never known to have any previous hemolytic epis...

Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzyme disorder in human. The aim of this study was to determine the prevalence of G6PD deficiency among children and evaluate its association with ABO/Rh blood groups. Method: Blood samples of 3401 asymptomatic children were analyzed and compared with 317 children who were admitted to hospital because of hemolys...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most prevalent human enzyme deficiency, affecting an estimated 400 million people worldwide. G6PD deficiency increases erythrocyte vulnerability to oxidative stress and may precipitate episodes of hemolysis when individuals are exposed to triggering agents. Although central retinal vein occlusion (CRVO) does occur in G6PD-deficient indi...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common hereditary enzyme disorder and more than 200 million people have a deficiency in this enzyme. It is a globally important cause of neonatal jaundice and causes life-threatening hemolytic crisis in childhood. At later ages, certain drugs such as antimalarials, and fava beans cause hemolysis among G6PD deficiency patients. The ...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common polymorphism and enzymopathy in humans, affecting approximately 400 million people worldwide. It is responsible for various clinical manifestations, including favism, hemolytic anemia, chronic non-spherocytic hemolytic anemia, spontaneous abortion, and neonatal hyperbilirubinemia. Understanding the molecular mechanisms under...

Deficiency in glucose-6-phosphate dehydrogenase (G6PD), an X-linked recessive red cell enzymopathy, is endemic in Southern Chinese. Universal screening of newborn is done in Hong Kong, Taiwan and Singapore, among other places. In Hong Kong, 4.8% of males are affected and seven common G6PD alleles account for over 99% of all defects. Male hemizygotes suffer from severe deficiency, while female h...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzyme defect, being present in more than 400 million people worldwide. The global distribution of this disorder is remarkably similar to that of malaria, lending support to the so-called malaria protection hypothesis. G6PD deficiency is an X-linked, hereditary genetic defect due to mutations in the G6PD gene, which ca...

Published by: Tehran University of Medical Sciences (http://ijp.tums.ac.ir) respectively. The overall incidence of G6PD enzyme deficiency was 12.96%. Of the total neonates 660 neonates suspected to have sepsis were referred to neonatal intensive care units, but finally after exclusion of other causes such as metabolic disorders and hypoxic ischemic encephalopathy, 110 patients (68 males and 42 ...

Background: Glucose-6-Phosphate dehydrogenase (G6PD) deficiency is an Xlinked recessive disorder expressed mostly in males. Prevalence of G6PD deficiency varies in different parts of the world’s according to ethnic variation. The incidence varies among different countries in the world and surveys report rates of less than 1% to 35%. The prevalence of G6PD deficiency in the Arab world has variou...
